The Lowdown

Alright mate, Rusty here. Let’s break down what’s cookin’ for the next couple of weeks.

We’ve got a solid run of surf coming up, but it’s a bit of a mixed bag with some real standout sessions if you time it right. The water temp is sitting pretty average for this time of year, so nothing wild there. The main focus is on Jaconé, which is exposed to the swell and picks up a good S to SE groundswell. The energy’s going to be pumping at times, with a massive 2167 reading on Thursday the 27th of August morning – that’s serious grunt. That morning, we’ve got a 8ft S swell with a 14-second period, which is a long-period groundswell. That’s powerful stuff, but at that size, it’s really only for experienced surfers. The wind is a light ENE cross-off, keeping things clean. That’s the standout session of the whole forecast, no question.

Thursday afternoon stays good with a 7ft S swell and offshore ENE wind, still a solid option for the crew who know what they’re doing. The energy is still high at 1766.

Friday the 28th of August sees the swell drop a bit, but the morning still offers a very clean 4ft S swell with offshore ENE wind. It’s a more manageable size, and the wave energy is moderate at 736. That’s a great morning for intermediates.

Saturday the 29th of August has a small 5ft E swell with a short 7-second period, so it’s not going to have much punch. The morning is clean with a light offshore NE breeze, but it’s a bit weak.

After that, things get a bit messy for a few days. Sunday the 30th of August is small and glassy in the morning, but the swell is tiny. Monday the 31st of August brings a welcome return of a 7ft ENE swell with an 8-second period and offshore NE wind. The energy is back up to 849, and the conditions are clean – that’s another good one for experienced surfers.

Then we hit a rough patch. From Tuesday the 1st of September through to Wednesday the 2nd of September, the wind shifts onshore and the swell is all over the place. It’s poor, choppy, and not worth paddling out for. Kite surfers might have a better time with the wind.

Thursday the 3rd of September offers a glimmer of hope with a glassy morning and a 6ft S swell. The energy is moderate at 714, and the glassy conditions are a big plus. That’s a solid morning session.

Friday the 4th of September has a clean 4ft SSW swell with offshore ENE wind, but it’s nothing special.

The second week is a bit mixed. Saturday the 5th of September is small and weak. Sunday the 6th of September has a building 6ft S swell with 12-second period, but the wind is cross-off, so it’s a bit messy. Monday the 7th of September looks promising again with a 5ft S swell, a 12-second period, and a light offshore NE breeze. That’s a clean, fun morning.

The rest of the week into the 11th of September has some small, clean mornings with offshore winds, but nothing that will blow your hair back. The 11th of September morning has a 3ft SE swell with a long 14-second period and offshore ENE wind – a clean, glassy little session if you’re desperate for a wave.

Overall, the best bets are Thursday the 27th of August morning and Monday the 31st of August morning for the bigger, cleaner swells. For the rest of us, Friday the 28th of August morning and Monday the 7th of September morning are the pick of the cleaner, smaller days.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
